McAfee virus removal

If you have actually installed McAfee AV on your Mac, and have already deleted its uninstaller, there are a few methods to try to remove all of the remnants of this app.

They include:

• Re-install McAfee. Once re-installed, locate the Uninstaller, and run it.
• Run an EtreCheck report. This report should expose all of the locations on your Mac where McAfee installed itself. EtreCheck is a diagnostics tool developed by a valued forum member used to troubleshoot issues with a Mac, but it will also come in handy for locating "hidden" files.

I understand that you installed the worthless "McAfee" product on your Mac, and you deleted its uninstaller. Is that correct?

Or are you simply encountering these equally worthless scam Notifications?
